GRAIN-SEPARATING MECHANISM FOR TRAVELING THRASHERS.

SPECIFICATION forming part of Letters Patent No. 445,112, dated January 20, 1891.

Application filed March 19, 1890. Serial No. 344,582. (No model.)

To a whom it may concern.-

Be it known that I, LOREN II. HILL, a citizen of the United States, residing at Oakdale, in the county of Stanislaus and State of California, have invented certain new and useful Improvements in Grain-Saving Devices for Traveling Thrashers; and I do declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same, reference bei n g had to the accompanying drawings, and to the let ters of reference marked thereon, which form a part of this specification.

My invention relates to an improvementin the grain-separating mechanism of a traveling thrasher; and it consists in the combination and arrangement of devices that will be more fully set forth hereinafter, and particu larly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of the rear portion of a thrashing-machine embodying my improvements. Fig. 2 is a front elevation of the transverse casing, showing the side Wall broken away to illustrate the reciprocating mechanism. Fig. 3 is a plan view of the grain-board and the reciprocating partitions or flanges thereon, the flexible connections of the latter being illustrated in dotted lines.

Referring to said drawings by letter, A is the trunk of the thrasher, suitably mounted on a frame and wheels.

Bis a shoe of any ordinary suitable pattern, located, as usual, within the trunk near its rear.

C is a cross-box or casing at the top of the trunk A near its rear end. It contains a large roller 0', having the bearings of its shaft in the blocks d, which slide back and forth upon tracks E, attached to the sides of the box O, being actuated in connection with a system of cords, Weights, and pulleys by the swaying of the machine. Forked hooks c are attached one to each of the ends of the blocks d and have attached to their hook ends cords D and G, the former of which passes over corner pulleys D in the jaws of the vertical rods D, attached to and depending from the top of the box 0, and having weightsfat the lower ends within drums F, which are suspended one at each end of the box 0 and are provided with rubber bumpers g at their bottoms to break the fall of the weights F.

The cords G make their turns at the corner pulleys G, attached to cleats e, which are secured to the sides of the box O, and passing downward outside the trunk A enter it over corner pulleys G j ust beneath the grain-board II, which is provided with three laterally-movable regulating discharging flanges II, the center one of which is provided with a de pending pivot post bearing in the grain-board, which has rigidlysecured to its lower end a lever II, which is provided with an eye at its free end, to which are secured the ends of the respective cords G.

The center flange H is provided at its upper end with a flat T branch, to which are pivoted the inner ends of the rods H the outer ends of which are respectively connected in a pivotal manner to the upper ends of the outer flanges, as illustrated in Fig. 3.

At the back of the grain-board and extending the full length thereof is an overhanging sheet-iron protector I, which prevents the grain from falling among the connecting-rods of the flanges or partitions I-I'.

Near the ends of the tracks E are located cross-bumpers C of rubber or other suitable material, suspended in position by cross-rods, which may be moved back and forth in slots in the sides of the box 0. The ends of these rods outside the box 0 carry wooden guards L of sufficient size to exclude dust from entering the box through the slots.

hen the machine is traversing uneven lands, the weights f will draw the wheel 0' back and forth, causing the cords G to actuate the flanges l-I and move them in such direction as to discharge the grain at the higher side of the shoe, thus preventing it from being discharged on the depressed side of the shoe and accumulating there, clogging the sieves, and being thrown off the sieves and wasted. The position of the bumpers O regulate the pull of the wheel O upon the cords G and D and control the movements of the flanges H.

The drums F maybe located above the box 0, as shown by dotted lines F, in which event pulleys would be required at the tops to accommodate the cords D Having thus described my invention, whatI claim as new is 1. In a thrashing-machine, the combination, with a grain-shoe and a grain-board arranged above said shoe and carrying transversely-movable flanges thereon, of a roller movable transversely with respect to the thrasher in a casing above the grain-board, the weights connected with said roller and adapted to shift the same,'and the cords connecting the flanges of the grain-board with said roller, whereby said flanges are shifted upon the grain-board, substantially as and for the purpose specified.

2. A grain-saving device adapted to travelingthrashers, consisting of the box 0, mounted upon the top of the trunk A and containing the roller 0, having its shaft-bearings in the blocks d, adapted to slide back and forth with the swaying of the machine upon the tracks E, attached to the sides of the box 0, such roller 0' being actuated by cords D passing over rollers D in the forks of the rods D,

. suspended from the top of the box 0 and having weights f at their lower ends within drums F, attached to the ends of the box 0, the drums F, having the rubber bumpers g at their bottoms, and the cords G, reciprocating with the cords D and causing the flanges H of the grain-board H to move with the sway of the machine,-substantially as described and set forth.

3. The combination, substantially as described, of the trunk A, the shoe B, the grainboard H, provided with the swinging-flange system H II H the box G, containing the roller 0, the weights F, connected to said roller and adapted to operate the same, and connecting pulleys and cords actuating the swinging-flange system of the grain-board H.

4. The grain-board H and its back I, in combination with the flanges H, the rod H rigidly attached to the center flangeH', the conmeeting-rod H flexibly attached to the back ends of the flanges H, and means for automatically shifting the flanges upon the grainboard, substantially as and for the purpose specified.

5. The combination,with the rollerO,adapted to slide back and forth with the blocks d in the casing O, of the transversely-arranged bumpers 0 mounted on a transverse shaft adjustable in longitudinal slots in the side walls of the casing, and the guards L, covering said longitudinal slots and adapted to prevent dust from entering the casing, substantially as specified.

- In testimony whereof I affix my signature in presence of two witnesses.

LOREN H. HILL.
